Abstract: In the title complex, [Cu(C₁₁H₉ClN₃O₂)₂]·4H₂O, the Cu^II atom is in a distorted octahedral coordination environment, coordinated by four N atoms and two O atoms from two tridentate 3-chloro-6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands. The molecules are linked via intermolecular O-HO hydrogen bonds involving water molecules to form extended chains along [010], and there are short ClCl contacts [3.153 (4) Å].
